Answer:
x=17
Step-by-step explanation:
See those same little "triangles" on each right end of the horizontal lines? That means that the horizontal lines are parallel. And the vertical line that passes through both of them is called a transversal. Whenever we have that situation - where parallel lines are being intersected by a transversal - we can then know which angles are equal to each other using some postulates.
The angles with the given equations shown are corresponding angles. We know this because they are in the same matching corners created by the intersections. And by using the Corresponding Angles Postulate, which states that corresponding angles are congruent (or equal) we then know that 5x-25 and 3x+9 must be equal to each other, too.
From there, we can set up an equation to find x. Just set them equal to each other like so and solve:
Therefore, x = 17. Please don't hesitate to ask any questions!
Answer:
The Total distance she travel fro work is 30 miles .
Step-by-step explanation:
Given as :
the total time taken to cover distance = 45 minutes
Let The total distance cover = D miles
The distance cover at the speed of 32 mph = miles
The time taken to cover miles distance =
hour
Distance = Speed × Time
∴ = 32 mph ×
h
or, = 16 miles
Again ,
The distance cover at the speed of 56 mph = miles
The time taken to cover miles distance =
hour
∴ = 56 mph ×
h
or, = 14 miles
So , The total distance she travel for work = +
Or, The total distance she travel for work = 16 miles + 14 miles = 30 miles
Hence The Total distance she travel fro work is 30 miles . Answer
